Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a seat belt buckle storage device for storing a seat belt buckle at a position where it does not interfere with the back seat when the back seat of a vehicle seat is tilted to the cushion seat side.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, in a folding seat of a commercial vehicle or the like, a seat belt buckle into which a seat belt fitting is inserted is provided on a side surface portion of a cushion seat in a self-supporting manner. FIG. 4 is a perspective view showing an arrangement state of a conventional seat belt buckle 22 in a foldable seat 21 of a commercial vehicle or the like.

As shown in FIG. 4, a seat belt buckle 22 is attached to each side surface of the cushion seats 23 of the adjacent foldable seats 21 in a self-supporting manner. The seat belt buckle 22 is required to be self-supporting in accordance with the regulations. On the other hand, the cushion sheet 23 and the back sheet 24 of the seat 21 are provided with large hollows 23A and 24A on the opposite side surfaces thereof. This gouging 23A is formed to secure a space for disposing the seat belt buckle 22, and the gouging 24A is provided with the back sheet 24 when the back sheet 24 is tilted forward. -To secure a space for avoiding the interference of the belt belt buckle 22 and the sheet belt buckles 22.

[0004]

[Problems to be solved by the device]

 In order to arrange the seat belt buckle 22 in the conventional vehicle seat 21 in a self-supporting manner, the large cushions 23A and 24A described above are formed on the side surfaces of the cushion seat 23 and the back seat 24 of the seat 21. There is a need. Therefore, there is a problem that the cushion sheet 23 and the back sheet 24 of the seat 21 are short in the width direction, the effective area is small, and the riding comfort is poor. In addition, since the seat belt buckle 22 is projected, the seat belt occupant's buttocks interfere with each other when seated, which makes it difficult to sit down, and sometimes the seat belt buckle 22 is damaged.

Therefore, in the present invention, it is a technical problem to be solved that the seat belt buckle is rotated so as not to project from the upper surface of the cushion sheet so as to be stored.

[0006]

[Means for Solving the Problems]

 The technical means for solving the above-mentioned problems is to install a seat belt buckle storage device for a vehicle seat, and a seat belt buckle into which a seat belt insertion fitting is inserted, above the cushion seat upper surface of the vehicle seat. The structure is such that it can be rotated to a position where it does not come out, and a rotation storage mechanism for storing it in that position is provided on the cushion seat side of the vehicle seat.

[0007]

[Action]

 According to the seat belt buckle storage device for a vehicle seat having the above structure, the seat belt buckle is provided even if the back seat is tilted forward because the turning storage mechanism is provided on the side of the cushion seat of the vehicle seat. Can be swung to a position where it does not interfere with the back seat and stored, and it is possible to avoid interference between the seatbelt and the seat belt buckle.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the overall configuration of a foldable vehicle seat 1. As shown in FIG. 1, a hinge cover 3 for covering a hinge attached to a frame (not shown) of the cushion sheet 2 of the vehicle seat 1 is a side surface of the cushion sheet 2 and the back sheet 4. It is arranged over the section. The hinge cover 3 is formed in a box shape, has a space formed therein, and has an opening 3A formed on the upper surface.

The seat belt buckle 5 protruding from the opening 3 A of the hinge cover 3 is attached to the tip of the arm 6. The seat belt buckle 5 is to be fitted with a seat belt fitting (sheet belt tongue) not shown.

FIG. 2 is a perspective view showing an arrangement state of the seat belt buckle 5 and the arm 6 in the hinge cover 3. 3 is a sectional view taken along the line AA in FIG. The base end of the arm 6 is attached to the bolt 7. The bolt 7 is formed in a stepped shape as shown in the sectional view of FIG. That is, the bolt 7 is threaded at its tip, while the lower portion 7A of the neck, which is formed in a circular shape thicker than the threaded portion, is not threaded. A hole opened at the base end of the arm 6 is inserted through the lower neck portion 7A of the bolt 7, and the arm 6 is rotatably attached about the lower neck portion 7A of the bolt 7. .

The bolt 7 has a tip screw portion inserted through a cushion frame 8 of the cushion sheet 2 and is fixed by a nut 9. As shown in FIG. 3, a spring washer 10, a flat washer 11, a washer 12, a wave washer 13 and the like are interposed between the head of the bolt 7 and the nut 9.

As described above, the seat belt buckle 5 is rotated about 60 degrees forward of the vehicle by rotatably attaching the base end portion of the arm 6 to the lower neck portion 7A of the bolt 7. As shown in FIG. 2, the seat belt buckle 5 is stored in the space position of the hinge cover 3 so as not to protrude above the upper surface of the cushion sheet 2.

The rotary storage mechanism according to claim 1 is constituted by the spring washer 10, the flat washer 11, the washer 12, the wave washer 13 and the like between the hinge cover 3, the bolt 7 and the nut 9. ing.

As shown in FIG. 2, in a state where the seat belt buckle 5 is stored in the space position of the hinge cover-3, in order to maintain the stored state, the stopper portion is provided on the opening surface of the hinge cover-3. 14 is formed so as to come into contact with one surface of the seat belt buckle 5. The reason why the seat belt buckle 5 can be located below the stopper portion 14 is that the arm 6 can be easily tilted in the direction perpendicular to the rotating direction. .

[0015]

[Effect of device]

 As described above, according to the present invention, the seat belt buckle into which the fitting for the seat belt is inserted is made rotatable to a position where it does not come out above the upper surface of the cushion seat of the vehicle seat, and the seat belt buckle is placed at that position. The seat belt buckle does not interfere with the back seat even when the back seat is tilted forward, and the seat belt buckle does not interfere with the seat occupant's hips because the turning storage mechanism for storing the seat is installed on the cushion seat side of the vehicle seat. It is possible to avoid the interference between the seat belt buckle and the seat belt buckle, and further it is possible to prevent damage to the seat belt buckle. Further, since the amount of cushioning of the cushion sheet and the back sheet can be reduced, the effective areas of the cushion sheet and the back sheet are increased, and the riding comfort of the vehicle is improved.
